Benefits of technology

[0019]Embodiments of the invention may utilize various bit efficiencies to more efficiently generate the control information. For example, the control information may comprise a plurality of commands, wherein at least a subset of the commands has associated data fields. Each of the commands may comprise a plurality of bit portions of a uniform length. Also, each of the data fields may comprise a plurality of bit portions having uniform length. In one embodiment, a firs

Problems solved by technology

A few bits are reserved for adding functionality, a few enumerated parameters support multiple options, but overall the changes supported are very limited.
The developers add this limited flexibility to the system in places they think are likely to change.
There are two types of changes needed that cannot be planned for; unforeseen problems with the system and new technology innovations.
Flexible, extensible method

Embodiment Construction

[0047]A communication system, such as a broadcast system, may typically include a framework for communicating some sort of content or service(s). A communication system may additionally include a signaling framework to provide information to receivers about the content or service(s). Any communication system with even minimal complexity or which may be expected to change over time may need to provide such information to enable a receiver to use the content or service(s); for example, a signaling framework may enable a receiver to tune to an offered service, to extract the service from the transport, and present it to a user. One specific example of a communication system is an audiovisual broadcast system, e.g., a digital television broadcast system. Many of the embodiments described herein may be illustrated in light of such an exemplary system, although the embodiments may also be applicable to other communication systems.

Abstract

First control information, generated according to a first protocol version, for configuring an audiovisual device to present a multimedia stream, may be generated. A first data structure specifying that the first control information is of the first protocol version may be generated. A plurality of packets, including a multimedia stream, the first control information, and the first data structure, may be generated and transmitted. Second control information, generated according to a second protocol version, for configuring an audiovisual device to present a multimedia stream, may be generated. The first data structure may be modified to include information about the second control information. A second plurality of packets, including the modified first data structure, the first control information, a multimedia stream specified by the first control information, the second control information, and a multimedia stream specified by the second control information, may be generated.
